A knotted rope toy with a tennis ball is a type of dog toy that combines the chewable texture of a rope. 
Dogs enjoy playing with rope toys because they can chew on them, tug on them, and use them to play games of fetch.
The size of the toy should also be appropriate for your dog's size and strength. It is also important to supervise your dog's use of the toy to ensure that they do not swallow any small parts or become entangled in the rope.
Overall, a knotted rope toy can be a great addition to your dog's toy collection, providing them with a fun and interactive way to play and exercise.
